'10PCS Mini Pocket Survival Button Compass for Bracelet Hiking Camping Outdoor' off eBay from Delhanway2009, 99p and free delivery (arrived in 10 days from Hong Kong) Certainly wouldn't want to try and find the source of the Nile using one but all ten point in the same direction when laid out on the table and read true with the Silva. I got them for fitting into sticks and at 10p a time I'm more than satisfied. just thought it worth a mention as several have spoken recently about carrying/wanting a compass when using the Tube etc. Actual compass is the size of a penny and they are made so they can will slide onto a watch strap.
